This invention relates to devices for manually operating automaticmachines for adjusting purposes;

The invention herein contemplated is especially adapted for machines forautomatically linking sausages as described in application for U. S.Letters Patent, Serial No. 263,364, filed March 22, 1939 and issued asPatent No. 2,228,075 on Januaryl,l941.

In such machines, manual adjustments are required from time to time.Heretofore, such manual adjustments have been made with appreciabledifficulty and inconvenience, since the normaloperation of the machineis by motor and the gearing arranged accordingly.

It is, therefore, an object of this invention to provide a device formanually adjusting a machine conveniently and rapidly without regard tothe normal motor operation thereof.

A further object is the provision of a manual adjusting means for amachine which is normally held in an inoperative position when themachine is being driven by a motor.

These and other advantageous objects, which will later appear, areaccomplished by the simple and practical construction and arrangement ofparts hereinafter described and exhibited in the accompanying drawing,forming part hereof, and in which:

Fig. 1 is a front elevational view of a machine embodying the invention.

Fig. 2 is a side View of a machine embodying the invention, and

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2, of a handlearrangement for manually operating a machine in accordance with theinvention.

Referring to the drawing, there is shown an operating motor I, having ashaft 2, to which is fixed a gear 3, in mesh with a gear 4 attached tothe shaft 5, carrying a bevel gear 6 engaging a bevel gear 6' fixed to ashaft 1 at right angles to the shaft 5. The shaft 5 passes through asupporting plate 8, which is secured to a housing 25, and is journalledin a sleeve 9 having a flange It] and encircled by a compression springI I which abuts the flange l and the shoulder I2 on a casing I3, inwhich the sleeve 9 and spring H are positioned. The outer end of casing13 is provided with an end plate M.

The end of shaft has diametrically arranged therein a short bar l6 whichis held in place by a pin ll. Integral with casing I3 and dependingtherefrom is a handle l8 having a knob 19.

Extending inwardly from the wall of easing l3 sion spring 5 Claims. (oi.lag-c7) is a pin 15 adaptedto engage the bar 5, and the wall of thecasing [15 is also provided with a circumferentialgroove 2!] receiving aplunger 2| encircled by a compression spring'ZZ mounted in a block 23,the plunger 21 having a handle 24, see Fig.3. 7

In operation, the bevel gears'B and 6' are driven by the motor I throughgears 3 and 4. When it is desired to manually adjust the machine, thehandle 24iis grasped to move the plunger 2| out of the circumferentialgroove 20 against the action of spring 22 to enable the casing l3 to bepulled outwardly against the action of compres- II as indicated indotted lines in Fig. 3. When the casing I3 is pulled outwardly, the pinl5 will engage the bar I6 to enable the shaft 5 to be rotated by thehandle l8, I9. By this arrangement, the shaft 5 can be rotated tooperate gears 6 and 6 to rotate shaft 7 and manually efiect whateveradjustment may be necessary. As soon as the handle l8, I9 is released,casing l3 will be automatically returned to its normal inoperativeposition by the action of spring I l and held in this position by theplunger 2| in the circumferential groove 20.

From the above description it will be seen that there has been provideda handle arrangement for adjusting manually an automatic machine, thehandle and associated parts being so constructed and arranged that theywill not interfere with the normal operation of the machine and areeffective only when the handle is moved to a predetermined position andmanually held in such a position during the manual adjusting operation.

In automatic sausage linking machines, due to the accidental bunching ofsausage in the machine from time to time, it is necessary to stop themachine and manually readjust the various parts. Also, a manualadjustment is necessary in adjusting the machine to link sausages ofdifferent lengths. Consequently, the device herein disclosed is ofconsiderable importance and convenience in a machine of the typeconsidered.

The foregoing disclosure is to be regarded as descriptive andillustrative only, and not as restrictive or limitative of theinvention, of which, obviously, many embodiments may be considered,including many modifications, without departing from the spirit andscope of the invention herein set forth and denoted in the appendedclaims.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent, is:

1. In a device of the class described, a shaft, a

sleeve in which said shaft is journalled, said sleeve having a flange atone end thereof, a rotatable and axially shiftable casing surroundingsaid sleeve and having a shoulder, a compression spring encircling thesleeve and abutting said flange and shoulder, a bar fixed to one end ofthe shaft, a pin extending inwardly from the casing and adapted to havedriving engagement with the bar, said casing having a recess in theouter wall thereof, and a spring pressed plunger adapted to bepositioned in said recess to hold the casing in a definite position sothat the pin will not engage the bar.

2. In a device of the class described, a shaft, a sleeve surroundingsaid shaft, a rotatable and axially shiftable casing surrounding thesleeve, means on the casing for drivingly engaging and rotating theshaft when the casing is in a predetermined position, spring meansengaging the sleeve and the casing to normally hold the casing in aposition whereby there will be no engagement between the casing and theshaft, and a spring pressed detent engaging the casing to hold thecasing in the last mentioned position.

3. In a device of the class described, a shaft having a bardiametrically arranged in one end thereof, a rotatable and axiallyshiftable casing having a pin projecting inwardly therefrom and adaptedto have driving-engagement with said bar, a handle attached to saidcasing, resilient means for normally urging the casing so that the pinwill not engage the bar, and a spring pressed detent adapted to engagthe casing to hold the casing in the last mentioned position.

4. In a device of the class described, a sleeve having a flange, arotatable and axially shiftable casing having a shoulder thereon andencircling able and axially shiftable casing, a handle attached to saidcasing, a sleeve positioned in the DANIEL DOUGLAS DEMAREST. CARLBERENDT. WILLIAM KARIUS.
